해결방법
This was answered for me on Stack Overflow:
http://stackoverflow.com/questions/3...s-into-eclipse
"All the baseline default.properties needs is a line like:
target=android-8"
You can copy another projects' default.properties into your project (choose one with the same API Level that you want). Then restart of Eclipse to rebuild the workspace.
NB you may find that your
src folder includes a R.java file. You need to delete this as it is automatically created in the
gen. Having two copies will generate an error.
